23.1 Trace Connections from Design Hierarchy

Start by inspecting the module hierarchy in the
Design Hierarchy View. All traces are going to be computed on this design hierarchy.

You can trace across the whole design (when you pick a top module as the
hierarchy root) or focus on a specific module in the design (when you pick that module as the
hierarchy root). The
Design Hierarchy View documentation provides more details on how to populate this view.

Select an instance and click on the
Show/Hide Ports button in the toolbar.

Then
right click on a port and select one of the trace kinds, for example
Trace Drive and Load.
